Australia Act 1986
03 March 1986
Australia becomes independent from the British Parliament and courts.
The Australia Act 1986 was the final step in Australia’s constitutional independence from Britain. This Act and the 6 similar Acts passed by the state parliaments made all Australian law independent of the British Parliament and legal system. It also stopped appeals from state courts to the British Privy Council. Together with the Australia Act 1986 (UK), the 7 Acts brought the states in line with the Australian Government’s relationship with Britain.
After the Statute of Westminster Adoption Act 1942 Australia was independent from Britain but the states were still subject to some aspects of British law. Despite the changes that had taken place at the national level since Federation, certain state bills still required the monarch’s approval and the monarch could disallow any state law within 2 years. States gave advice to the monarch through the British Foreign Minister, not an Australian minister.

Description
A formal proclamation document signed by Her Majesty Queen Elizabeth II, Queen of Australia, dated 2 March 1986. This Proclamation fixed 3 March 1986 as the date the Australia Acts would commence. The British Parliament and each Australian state passed individual Acts before the federal Parliament passed its own. None of the Australian Acts had a start date, as they all had to commence on the same day as proclaimed by the Queen. The Australia Acts ended all remaining legal ties between Australia and the United Kingdom, including appeals to the Privy Council, and affirmed Australia's full legislative and judicial independence.
